This report presents a comprehensive collection of searches for new physics performed by
the ATLAS Collaboration during the Run 2 period of data taking at the Large Hadron …

The existence of nonzero neutrino masses points to the likely existence of multiple Standard
Model neutral fermions. When such states are heavy enough that they cannot be produced …

Measurements and searches performed with the ATLAS detector at the CERN LHC often
involve signatures with one or more prompt leptons. Such analyses are subject to 'fake/non …

The CDF Collaboration has recently reported an updated result on the W-boson mass
measurement, showing a 7 σ deviation from the standard model prediction. The discrepancy …

A bstract We comprehensively study all viable new-physics scenarios that resolve the muon
(g− 2) μ anomaly with only Standard Model singlet particles coupled to muons via …

A bstract The type-II see-saw mechanism based on the annexation of the Standard Model by
weak gauge triplet scalar field proffers a natural explanation for the very minuteness of …

A bstract We initiate the study of a new class of beyond the Standard Model states that we
call “Loryons.” They have the defining characteristic of being non-decoupling, in the sense …

A bstract A search for vector-like leptons in multilepton (two, three, or four-or-more electrons
plus muons) final states with zero or more hadronic τ-lepton decays is presented. The …

A bstract We perform a classification of all potential supersymmetric R-parity violating
signatures at the LHC to address the question: are existing bounds on supersymmetric …

We calculate total and differential cross sections for the pair production, at the Large Hadron
Collider, of exotic leptons that could emerge from models with vectorlike leptons and in type …
